IMPROVED GRADING AND ROAD-SCRAPING MACHINE.

Specification forming part of Letters Patent No. 43,422, dated July 5,1864.

T0 all whom it may concern:

Be it known that I, EDWARD H. MORE, o Moresville, in the county ofDelaware and State of New York, have invented a new and Improved Gradingand Road-scraping Machine 5 and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadtothe accompanying drawings, making a part of this specification, inwhich- Figure 1 is a plan or top view of my invention, with the partsadjusted in a workin g po sition; Fig. 2, a side sectional view of thesame, taken in the linea fr, Fig. l; Fig. 3, a detached inner side viewof one of the wings o: Scrapers of the same 5 Fig. 4, a diminished planor top view ofthe same, showing its op eration.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to a new and improved machine for grading orscrapingroads; and it consists in constructing and arranging the partsin such a manner that a greater or less pressure may be brought to bearon the .Scrapers as circumstances may require, and

the Scrapers also be capable of being adj usted, when not desired foruse, out of a working position, so that the machine may be readily drawnfrom place to place, one of the. scrapers being also so constructed thatit may be adjusted to work over Vslopin g or inclined ground.

Toenable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a Vs`haped platform, which constitutes the body or frame ofthe machine, and which is mounted on three wheels, a al b, two of thewheels, a c, beingat the front of A, one ateach side, and the other, b,nearits back end.

B is a draft-pole connected. to the front end of A, and G iS a polewhich extends beyond the rear A, andl by which the operator guides themachine when the latter is performing its work.

D D are two wings or Scrapers, placed one at each side of the platform Aat a suitable distance from it, and connected to it by arms c, which aretted loosely on rods d at the sides of A, so that the wings or Scrapersmay be turned upward and rest on the body A when they are not designedtobe used. The wings or Scrapers are each braced by a chain, E, from thedraft vpole B, and one of the wings or Scrapers, D, is formed of a plankshod at its lower part with metal, and having its upper edge slightlyinclined downward towards its back edge. The other win g or scraper, D',is composed of two parts, e e', connected by a joint, f, the front part,e, having a bar, F, attached to it which extends the whole length of Dat its outer side, the bar F having a plate, G, attached to it which maybe fitted in any of a series of notches in an upright bar, H attached tothe back part, e, of D', the latter, like D, being shod with metal atits lower end.

By adjusting the bar F higher or lower the front part, e, ofthe scrapermay be placed in a more or less inclined position, So that it may workin the hollow or ditch at the sides of the road. (See Fig. 3, in whichthe part e of the scraper D iS shown, somewhat inclined downward, inred.) v

The device is rst drawn along at one side of the road,'and the earthscraped up in a ridge or windrow by the Scrapers D D. The device is thendrawn along at the opposite side of the road and another ridge orwindrow formed, and thesethe windrows-rare gathered into one at thecenter of the roadv when the device is drawn over the center of thelatter, (See Fig. 4, in which the several windrows of earth are shown,and also the several positions of the device.)

The wings or Scrapers have a aring position, each one being parallel, ornearly so, with the side of the platform A, to which itis connected, aspace being allowed between the back ends of the Scrapers to admit ofthe escape of the dirt.

On the platform A there are placed two arms, F F', the front ends of thelatter being secured to the former by pivot-bolts f. rlhese arms passthrough guides g on the platform, and the arms are Sufliciently long tobe turned upon the tops of the scrapers D D when desired. When the armsF are not on the scrapers, the latter press on the earth with a weightdue to their own gravity only 5 but when a greater pressure is requiredthe arms F are turned or moved so as to bear on the upper edges of theScrapers and transmit the weight of the platform A with its attachedparts to the Scrapers, the arms F being moved for--1 ward according tothe amount of increased pressure required.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The two Scrapers D D', connected to the platform A,substantia11y asshown, in connection with the arms F F', all arranged substantially asand for the purpose herein set forth.

2. The adjustable wing or scraper D', constructed of two parts, e e,connected by ajoint, f, and used with the bar F, or its equivalent,substantially as and for the purpose specified.

EDWARD H. MORE.
